Newbie here and potential first time Audi owner.
​​​​Im hoping for expert inputs into Audi ownership​.

​​​​I currently have a 5 year old outback and looking to get either the 2018 RS3 or 2018 Q7 w/air suspension as a second vehicle to keep long term - minimum 10 years.

I don't have any experience with Audis at all and I've been reading a lot about both vehicles in terms of reliability and longevity. There's not a lot of reliability reviews out there since both are relatively new. I do know that extended warranty is a must to keep these cars long term but other than that, what else should I know about owning one of these vehicles?

Objectively, which one will last longer and has reasonable long term maintenance costs?

Thanks in advance​ for the input and my apologies if my newbie questions have offended anyone.
